Application filed October 16, 1920. Serial No. 417,340.

To all whom it may concern Be it known that I, HENRY J. SHAvnns, acitizen of the United States, residing at Goldsboro, in the county ofWayne and State of North Carolina, have invented certain new and usefulImprovements in Lubricators, of which the following is a specification.

My invention relates to a new and useful improvement in lubricators thatare designed to force heavy oil and flake graphite to the cylinders of alocomotive.

An object of the present. invention is to provide a lubricator whereinthe oil and flake graphite is first poured into a funnel or large cupfrom which it is drawn into a reservoir in the form of a cylinder. Inthis cylinder is a piston which is to be under a slight pressure, and inthe bottom of the cylinder is a port with an adjustable valve therein sothat the amount of oil or graphite fed therefrom may be regulated asdesired. From the first mentioned cylinder the oil is led into secondcylinders from which it is forced out by compression to a pipe leadingto the cylinder of the loc0mo tive. These last two mentioned cylindersbeing operated by a small motor.

Still another object of the present inven tion is to provide alubricator that is very compact in nature, highly efficient and capableof forcing the oil and graphite under compression to the cylinders ofthe locomotive.

Still another object of my invention is to provide a lubricator that issimple in operation, relatively cheap to manufacture and quickly andreadily assembled.

With these and other objects in view asv will be disclosed as theinvention proceeds my invention consists of certain new and novelconstructions and combinations of parts as will be hereinafter morefully described and pointed out in the drawings.

Figure 1 is a side elevation partly in section of my improvedlubricator;

Fig. 2 is an end view partly in section; and

Fig. 3 is a detail of the worm and crank arms for driving thelubricator.

Referring now in detail to the several figures there is shown a base 1,on which is mounted a motor 2, although it is to be understood that anyform of driving means may be employed.

A standard 3 is shown in which is mounted the worm gear at which isdriven by the worm 5 of the motor shaft.

Two crank arms (5 are revolved bv the gears to which cranks are securedand connecting rods 7, the same in turn being con nected to the head 8mounted on the slide bar 9. I

This bar is supported at its one end by the standard 10 and at its otherby the malrrhousing 11 of the lubricator. I

Th1s housing 11 is in turn supported by the brackets 12 which are boltedto the base 1, as shown. Mounted in this housing are the two cylinders13 and l t to which are bolted the heads, 15 and 16. As the cylindersand heads and cooperating plungers are identical a description of onewill suflice. Referrmg now in particular to Fig. 1 it will be seen thatthe head 16 extends inwardly for a greater portion of the cylinder, isprovided with the packing rings 1? and is beveled at its inner end andprovided with the projecting portion 18.

Operating in the cylinder is the hollow plunger 19 which is providedwith the upper or lnlet port 20 and with the larger outlet port 21formed in its under surface. Connected with this plunger is the rod 22which extends through the cylinder head 23 and the stuifing gland 24 andis fastened to the heretofore mentioned sliding head 8.

This hollow plunger snugly fits the head 16 so that when the same isoperated it will compress the air in the plunger on its for wardstrokeand form a vacuum on its rearward or back stroke.

Extending through the lower portion of the cylinder is the neath thesame is the check valve 26 secured to the coupling 27 in one side ofwhich may be secured a jet pipe 28 while another pipe 29 leads to thecylinder of the locomotive. Also leading to this coupling 27 (Fig. 2) isthe pipe 30 which is an auxiliary oil feed provided in case theoperating plungers should be in any way damaged or become inoperative.

Referring again to the several figures, it will be seen that bolted tothe housing 11 is the reservoir cylinder 31 in which is provided thepiston 82, and entering the head of this cylinder is a pipe 33 foradmission of a slight amount of steam. Secured at one side of this feedcylinder is the filling cup 84 with the valve 35 therein.

Extending through the base of the cylinport 25 and directly be der 31 isthe central discharge opening 36 and across which is placed the valve 37which. is regulated by the movement of a handle 38 connected therewith.

Below this valve is placed a sight tube 39 so that the flow from thereservoir cylinder may be seen and regulated as desired. Be

neath the valve 37 there is a small port 40 for the admission of aslight amount of'air, this port being connected to a check valve 51.

From the opening 36 extend the two feed channels e12 which lead to thetwo cylinders 13 and Also extending from the sides of the cylinder 31are the two pipe lines 30' in which are the valves 43 and the sights 44:to which are connected the aforementioned pipes 30 so that an auxiliaryfeed is provided, if ever necessary.

The operation of the lubricator is therefore as follows: Oil and flakegraphite or any other proper lubricant will be first poured in the cup34 and the piston 32 raised which will draw the same into the cylinder31, the valve of course afterward closed. Steam will then be admitted tothe pipe 33 so that a constant pressure will be kept on the piston.

The flow or feed of the lubricant will then be regulated by firstlooking through the sight 39 and turning the handle 38 on the valve 37,until the proper feed is determined. The motor will be started andpresuming the plunger 19 is in the position shown in Fig. 1, as it isdriven forward by the revolving of the worm gear 4 and its cooperatingparts, the air and the oil that has passed through the several ports,and has been drawn by the rearward movement of the plunger through theinlet port 20 into the plunger will be compressed. That is, as soon asthe port 20 passes the projection 18 and the feed channel 42, and thepiston will continue to compress until the discharge port 21 alines withthe port 25 when it will 7 be forcibly blown into the pipe 29 leading tothe cylinder of the locomotive. The jet pipe 28 being used if desired,to further force the lubricant to the cylinder.

As the plunger begins its rearwardv stroke the check valve 26 will closeand a vacuum will be formed in the plunger until the inlet port 20registers with the feed channel, when the oil will be drawn into theplunger and the operation repeated. A small amount of air will be drawnfrom the port 40 along with the oil from the reservoir which isdesirable. It will be seen that the flow of the lubricant is partly bygravity, partly by pressure of the piston in the feed cylinder orreservoir, and partly by the vacuum caused by the return stroke of theplunger, thereby assuring a proper feed of the lubricant; while the flowto the cylinders of the locomotive is assured by subjecting the oil andair to compression in the plungers and by providing a blower if founddesirable.

From the foregoing it will be seen that I have provided a lubricatorthat is positive in action; may be quickly regulated as to the properfeed, compact in nature, and efficient in service.

Also an auxiliary feed is provided so that in case of a break-down ofthe lubricator the cylinders of the locomotive may still be suflicientlylubricated until the lubricator isrepaired.

Many slight changes might be made in the arrangement and positioning ofthe parts without in any way departing from the spirit and scope of theinvention.
